Dak IX extra front switch question
I know these switches were placed to switch to new added channels. I never used this feature but does anyone know how it worked. The switch has only two positions. In the up position it seems like regular channels 1-40. I don't know what it would be if I put the switch in the lower position. I don't hear anything when in the lower position. How many channel should it be with the new ones? The wire on the switch does goes to a green wire in the pll circuit so its probably for channels. I do notice that if I change REGULAR channels it seems like I have to turn the set off and than on again to get it to receive on this channel. This could be another problem. ANY INPUT TO THE OUTPUT? Thanks Ron
